How it works

Drop a file. Get it back smaller, seconds later.

Every tool runs on your own device using the browser's built-in power, so there is no upload queue and nothing to trust us with.

Why LocalKit

Everything you need, nothing you don't

  • 100% private

    Files, tokens and code are processed on your device. Nothing is uploaded or stored.

  • Instant results

    No upload queue and no waiting for a server. Most jobs finish in under a second.

  • Works offline

    Once a page has loaded, the tool keeps working even without an internet connection.

  • Made for phones

    Every tool is designed for small screens, so you can fix a file straight from your gallery.

  • Free forever

    No sign-up, no watermarks, no daily limits and no "premium" version.

  • Built for learners

    Clear explanations, worked examples and live previews help you understand what each tool does.

Your files stay on your device

Most converters send your documents to a server. Here, the work happens inside your browser using the same technology that powers web apps like Google Docs. Bank statements, ID cards and contracts are processed locally and disappear when you close the tab.
